Models PA-31, PA-31-300, PA-31-325, and PA-31-350 airplanes. AD 96-12-12 currently requires a one-time inspection of the bulkhead assembly at fuselage station (FS) 317.75 for cracks and the installation of one of two reinforcement kits determined by whether cracks were found during the inspection. Since we issued AD 96-12-12, bulkhead cracks were found on airplanes that had complied with AD 96-12-12 and on additional airplanes not affected by AD 96-12-12. This proposed AD would require repetitive inspections of the bulkhead assembly at FS 317.75 for cracks, repair of cracks as necessary, and the installation of a reinforcement modification. We are proposing this AD to correct the unsafe condition on these products. 80 FR 76398 https://www.govinfo.gov/app/details/FR-2015-12-09/2015-30882 2015-30882 fr09de15-12 RIN 2120-AA64 4910-13-P Docket No. FAA-2015-7205 Directorate Identifier 2015-CE-025-AD https://www.govinfo.gov/app/details/FR-2015-12-09/2015-30882 https://www.govinfo.gov/content/pkg/FR-2015-12-09/html/2015-30882.htm https://www.govinfo.gov/content/pkg/FR-2015-12-09/pdf/2015-30882.pdf Air Transportation Aircraft Aviation Safety Incorporation by Reference Safety 3 p. 76398 76400 80 FR 76398 Title 14 Part 39 14 CFR Part 39 RIN 2120-AA64 Airworthiness Directives; Piper Aircraft, Inc.
